This bill, known as the Kay Hagan Tick Reauthorization Act, aims to extend and modify federal programs dedicated to combating vector-borne diseases. It specifically reauthorizes the national strategy and regional centers of excellence in vector-borne disease, alongside enhanced support for health departments. The legislation adjusts the funding for these critical initiatives, allocating $8,000,000 annually for the national strategy and regional centers for fiscal years 2026 through 2030. Concurrently, it provides $19,000,000 annually for the same period to assist health departments in addressing vector-borne diseases, with both allocations representing a reduction from previous appropriations. Additionally, the bill streamlines the composition of individuals involved in developing the national strategy, ensuring continued federal support for research, prevention, and public health efforts against these illnesses.
